" To all whom t may concern:

Be it known that I, LENA PERLMAN, a citizen of" the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Surgical Bakers, of which the following is a full, clear, and exact description, reference being had to thev accompanying drawings, which form av part of this specilication.

This invention relatesto an improvement in surgical bakers and is designed to provide a device of this character' which is adapted for the treatment of different portions of the body'.

The object4 of my invention is to provide a hollow,` truss structure, of arch form, which is arranged to span the body, or the limbs of the patient, and in which the lamps or treating elements are supported between the structural members, so that the treating elements are protected against in jury, while the patient is protected from the danger of direct contact with the treating elements.

A further object of my invention is to provide a light, rigid structure which will retain its shape when in use, so that the patient cannot be injured or burnt by the collapse of the instrument, as well as an instrument which can readily be handled and which will not buckle or bend by handling.

The precise nature of my invention will be best understood by reference to the accompanying drawings which will now be described, it being premised, however, that changes may be made in the details of construction, without departing from the spirit and scope of my invention as defined in the appended claims.

Fig. 1 of the drawings is a. perspective view of one form of my invention.

f Fig. 2 is aI face view thereof.

Fig. 3 is a sectional view on the line 3-3 of Fig. 2.

.Fig 4 is a similar view on the line 4-4 of Fig. 8.

In these drawings the reference character 10 designates truss forming members of arcuate form, there being one of such members at each end of the structure. These members are .formed of light material and I have found that libre is suitable for this portion of the structure when the device is properly braced. 11 and 11a are longitudinal tie bars connected to the compression portions of the members 10, and 12 are similar members connecting the tensionl portions of these same members to each other.

These members 11 and 12 are formed ofv is connected to a member 11, and extend in a radial direction to the one edge member 12. These members then extend over all of the members 12, and then extend in radial direction to the other member 11a.

These members 14 are secured to the dif ferent members 12 by means of screws 15, the arrangement being such that the members 14 tie the members 12 to each other and thereby reinforce each other, .while the members 111 are reinforced and retained in their posit-ions by the members 12. Mounted on the outside of the members 11 is a metallic reflector 16 which is secured in position by screws 17 which have a threaded engagement with the members 11. 18 are also reflector plates on the inner sides of the truss members 10 and which are held in position by the screws 13 which secure the members 10 to the members 11, 11a and 12.

Secured to the central member 11 by means of screws 19, is a handle 2O by which the baker can be carried.

21 are sockets secured to the truss members 10 and are connected to each other and a switch member 22 by suitable wires, and which sockets are arranged to receive electric light bulbs 23.

The various members are so placed that the lamp bulbs are guarded by the various structural elements, and the patient on whom the instrument is used is protected from coming in contact with the bulbs.

The advantages of my invention result from the provision of a surgical baker of arcuate form, built up of a plurality of structural elements 'to form a rigid and light structure which encase 'the lamps or treating elements, whereby the lamps are protected, as well as the patient from contact with the lamps.

Having now fully described my invention, what li claim and desire to protect by Letters Patent is :n

l. An arch-shaped surgical baker, having arcuate shaped end memb rs, an outer trame formed 0i structural elements connecting the outer edges olf the end members to each other, an inner irame formed of a plurality of spaced structural elements connecting the inner edges of the end members to each other at different points throughout 'the length of the end members, and lamps supported on one et said end members and eX- tending between the trames, the inner frame also iorming a guard tor lamps.

2. An arch-shaped surgical baker, having arcuate shaped end members, an outer frame formed ot structural elements connecting the outer edges or the end members to each other, a reflector secured to the outer iframe, an inner frame formed oit a plurality oit spaced structural elements connecting the inner edges of the end members to each other at dil'ferent points throughout the length or the members, and lamps supported on one of said end members and extending between the frames, the innei' trame also 'forming a guard Yfor lamps.

3. An arch shaped surgical baker, having arcuate shaped end members, a plurality oi' spaced longitudinal members connected to the outer edges of the end members, an are shaped reflector secured to the longitudinal members between the end members, a. plurality ot' longitudinal members secured t0 the inner edges of the end members forming an inner frame, a reflector on the inner vtace oit each end member held in position by being secured between the ends ot the longitudinal members and the end members, a plurality or' arcuate tie rods connected to the longitudinal. members of the inner trame, the ends of said tie rods extending in radial directions and being secured to longitudinal members connected to the outer edges I oi the end members, and treating elements supported on the ond members between the arc-shaped reflector and the inner lrame, the inner frame also forming a guard for the treating elements.

in testimony ci which invention, I have hereunto set my hand, at Philadelphia, on this twelfth day of August, 1920.
